Melting ice could cause gravity shift

I am not entirely sure I agree with this conclusion, but then I am not a scientist...


also think this topic should possibly be in the Natural Sciences section....
 
When they say: "This redistribution of mass would also affect the Earth's rotation", do they mean the direction? Like, instead of west-east, it would change to north-south or something like that?

I'm also not sure, is there a huge difference in weight between ice and water?
Does not add up.:confused:

I'm not scientist either, but from my understanding, how to you rotate an object in space? Its like an astronaught standing on the edge of a spaceship while moonkwalking and expecting the space ship to move. You'd probably need some external factor and the only one I can think of is the gravitational effect of the moon on earth? :confused:

Also, its ice right, so it must've been water at some stage?
 
I hate it when popular press items don't better state their sources and just say "scientists sa" or something. Where were these claims published?
 
JhatMan : when you're talking gravity, you're thinking closed system...

Everything effects everything else.... so the earth is effected by the sun, the moon, mars, venus, jupiter, etc etc.. even the minor gravitational effects by distant suns.....

Mila : there isn't a weight different between water and ice, but what the scientists are talking about is the redistribution of that mass from the pole into the oceans.... I still don't actually agree with their conclusion in as much as I don't think it required a news story.. if it does effect anything the effect won't be MASSIVE, and it will take a LONG time to happen. You don't melt that volume of ice quickly...

Get Chuck Norris to walk on it.
 
It's not just fundamentalist religious zealots who say the eschaton is imminent. Now we have fundamentalist scientistic zealots joining them. Apocalypse now!

For the rest of use, life continues as before. Most people see through this sort of nonsense.
 
Just as a note : Remember that the pull of the moon is responsible for our tides.
 
Pole shift hypothesis
The pole shift hypothesis is the hypothesis that the axis of rotation of a planet has not always been at its present-day locations or that the axis will not persist there; in other words, that its physical poles had been or will be shifted. The Pole shift hypothesis is almost always discussed in the context of Earth, but other bodies in the Solar System may have experienced axial reorientation during their existences.
http://en.wikipedia.org/wiki/Pole_shift

Effects of Arctic shrinkage include a marked decrease in Arctic sea ice; melting permafrost, leading to the release of methane, a potent greenhouse gas[19]; the release of methane from clathrates, leading to longer time-scale methane release;[20] the observed increase in melt on the Greenland Ice Sheet in recent years; and potential changes in patterns of ocean circulation. Scientists worry that some of these effects may cause positive feedbacks which could accelerate the rate of global warming. Current research shows arctic sea ice cover is shrinking somewhat more rapidly than predicted by the IPCC, while recent atmospheric methanes levels show little increase, and current atmospheric methane concentrations are far below IPCC projections.

Melting ice could cause gravity shift
The melting of one of the world's largest ice sheets would alter the Earth's field of gravity and even its rotation in space so much that it would cause sea levels along some coasts to rise faster than the global average, scientists said yesterday.

Does this mean the weather in the UK will get warmer, and the weather in SA colder ?? :)
 
It will happen on the 21.Dec. 2012 according to reliable sources in South America

Remember that the Antarctic ice sheet is 4 km thick in some areas (or was that 6km?), and covers a larger area than the continent itself. That's a lot of weight. If I'm not mistaken, the SANAE base (the old one) was built on permanent ice, a long way out at sea. I'll have to check on that though.

Ice floats in water right, that means ice is lighter than water. Failed scientist has failed :D
